State-of-the-art Dew Point Monitoring

The new generation of the SUTO dew point sensors have been redesigned from the ground up, offering compressed air users a plug & play solution to monitor their compressed air quality and purity. With the integrated pressure sensor, the S220 measures dew point, temperature and pressure in a single instrument.

Minimization of calibration intervals

Thanks to the reliable and long-term stable measurements, the S220 Dew Point Sensor reduces the maintenance cost to a minimum by increase calibration intervals.

Unique Triple Sensor

Our QCM sensor is the result of years of high-tech research and development. The sensor was especially designed for low dew point applications where other sensor types fail. The combination of QCM and the well-known Polymer sensor makes the S220 the world’s first model to measure accurate over the whole range, from -100 °C Td up to +20 °C Td by switching automatically between the two sensor elements as needed.

By fitting an additional optional pressure sensor into the measurement unit, SUTO is combining 4 sensor elements (Polymer, QCM, Pt100, pressure) into a single dew point sensor.

Various Output Connections

The S220 Dew Point Sensor is available with 2-wire or 3-wire analog 4… 20 mA output signals. It is also available with a Modbus/RTU digital interface.

By offering different output signals, users can profit from great flexibility and seamless integration into their process. They can be easily connected to the SUTO displays and data loggers S330/331 and S551, for optimal stationary or portable data logging, as well as to third-party devices.

Optional Display for On-site Values

The optional OLED display directly mounted on the sensor provides on-site real-time values. The display can be easily rotated by 340 ° to fit in any application. The display cover is made from robust Polycarbonate with ABS reinforcement to withstand harsh environments.

Robust Materials for Long-term Stable Measurements

The main body is made from high class aluminum alloy with a soft finish. The process connection material is 1.4301 (SUS 304) stainless steel, made to last forever. Top cover made from aluminum with the same quality as the main body.
